Wi-Fi Alliance Kicks Off A/C Certification Program

The Wi-Fi Alliance today launched its Wi-Fi Certified ac certification program. The new program is meant to ensure the compatibility of 802.11a/c Wi-Fi products across a range of consumer devices, such as smartphones, tablets, and laptops. Wi-Fi Certified ac devices will operate in two bands, 2.4GHz and 5GHz, and will be able to handle streaming content such as Ultra HD and 4K video. The Wi-Fi Alliance expects the first Wi-Fi Certified ac devices to reach the market during the second half of the year. Routers and access points will be the first devices to attain the new certification, but other consumer electronics hardware will follow shortly thereafter.
